Malolactic fermentation is a secondary fermentation where malic acid is turned into lactic acid by the Oenococcus oenibacterium. Many California Chardonnays exhibit the fully-bodied, buttery charateristics of malolactic fermentation. Wikipedia has a good article on the subject.

What is the significance of ML in the fermentation process of wine, and how does it affect the taste and quality of the wine in the bottle?

Malolactic fermentation (ML) is a secondary fermentation process in winemaking where malic acid is converted into lactic acid by bacteria. This process can impact the taste and quality of the wine by reducing acidity, enhancing complexity, and creating a smoother mouthfeel. ML can also contribute to the development of desirable flavors and aromas in the wine, ultimately influencing its overall character and aging potential.
